Series 0 does not have the TXIDLE status flag. The closest equivalent is TXC, but it isn't set until the first transmission completes, and is therefore not safe to use in PM suspend without also separately keeping track of whether the driver has ever initiated a transmission. For now, disable the TXIDLE check on devices that don't support it as a minimal fix for the observed build error. This is effectively equivalent to reverting the addition of PM support for these devices only. Since these devices don't have a low-power system timer implementation anyway, the lack of PM handling does not hurt anything. Signed-off-by: Aksel Skauge Mellbye <[email protected]>
